This study analyzes the impact of carbon capture and storage (CCS) power plants on greenhouse gas reduction in Europe under different climate policy regimes. The study uses the TIMES PanEU model to assess the costs and potential of CCS technology in achieving long-term GHG reduction targets. The results show that the success of CCS heavily depends on capture costs and GHG reduction targets, with CCS becoming essential in achieving a 60% reduction target by 2040. However, CCS costs may have more influence on market penetration than GHG reduction targets. In 2050, the climate regime determines the use of CCS, with reductions in capture costs leading to increased electricity consumption and nearly complete decarbonization of the public power generation sector.

Motivation and target • EU- 20-20 and 2°C targets of European Commission stated but post Kyoto long term GHG reduction obligation of European countries? • Hugh investments in European power generation sector to compen-sate decommissioning capacities and to enlarge generation system! • Carbon Capture and Storage (CCS) promising alternative for low carbon fossil fueled power generation?! Analysis of capture costs of CCS power plants and their impact on contribution of CCS power plants as a GHG reduction technology.

Conclusions • In 2030 CCS market share heavyly depends on capture costs and GHG reduction targets. CCS technologies face intersectoral competition. CCS costs may have more impact on CCS market penetration than GHG reduction targets. • In 2040 CCS becomes essential under climate regimes aiming minimum GHG reduction of 60% compared to Kyoto base. GHG reduction target determines primary level of carbon capture. Little influence of CCS costs on use of CCS technologies. • In 2050 climate regime determines use of CCS. Reductions of capture costs can lead to increase of electricity consumption. Nearly complete decarbonisation of public power generation.
